Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard as they set with heat, and whites form the light topping.
- Milk
- Forms the liquid base that the egg yolks thicken into custard.
- White sugar
- Adds sweetness and helps balance the richness of the custard.
- Vanilla extract
- Adds aroma to the custard.
The step that matters
Boiling the custard until it begins to thicken. Egg yolk proteins thicken the milk as they heat, but they can curdle and turn grainy if the mixture overheats or is not stirred. Stirring continuously keeps the heat even and the custard smooth.
